The wide dynamic range (WDR) function of a camera is intended to provide clear images even under back light circumstances where intensity of illumination can vary excessively, namely when there are both very bright and very dark areas simultaneously in the field of view of the camera. WDR enables the capture and display of both bright and dark areas in the same frame, in a way that there are details in both areas, i.e. bright areas are not saturated, and dark areas are not too dark. Pixim WDR Technology gives supreme image quality and the chart below shows comparison between Pixim WDR Camera and CCD Camera:

690HTVL-E High Resolution Technology

It's important to understand the inherent limitation placed on vertical resolution by an imaging
solution that relies on interlaced image capture. Analog CCD sensors used in video surveillance
cameras capture interlaced video using a process called line-pair summation. This improves
low-light sensitivity somewhat and acts as a low pass filter, but has a side effect of decreasing
the effective vertical resolution by 25%1. This means that a 480 line CCD sensor is limited to a
maximum vertical resolution of 360 lines and that the image’s total resolution is decreased by
25%. That’s unfortunate for the end user because DVRs and display monitors are very capable
of utilizing all 480 lines of vertical resolution. Imagers that perform progressive image capture,
as is the case with Pixim's Digital Pixel System® technology, maintain the full vertical resolution.

Pixim Cameras Allow You to Get the Best of Your DVR

In comparison with high-resolution CCD Cameras, Pixim cameras save you 19% (comparing with 600TVL and above CCD Camera) to 62% (comparing with 540TVL and less CCD Camera) of DVR storage space. This is because Pixim-powered cameras never take any artifacts and noise effects during the process of scaling the video to DVR hard drive.
